What We’ve Built
CommonHealth
Your health records, all in one place
Free Android app connecting people to 13,000+ U.S. providers, payers, and Medicare.gov. Built Android-first to reach the people most consumer health apps overlook.
JupyterHealth
Bring consented health data together for research, care, and AI
Open-source platform built with UCSF, UC Berkeley, Duke, 2i2c, and Project Jupyter to bring wearable, device, and EHR data into one secure, data science and AI-ready environment.
We also offer implementation services to help deploy and maintain JupyterHealth on your infrastructure.
SMART Health Card Verifier
Verify digital health credentials anywhere
Free, open-source verifier used worldwide. Works offline. No account required. No data leaves the device.
